Heat exchanger having air drying device

Abstract

A heat exchanger includes a container having an outlet and an entrance coupled to an inlet and an exit, a receptacle having an entering port and a discharging port for circulating a fluid medium and having an entering opening and a discharging opening. A casing is disposed between the container and the receptacle and includes a passage coupled between the outlet of the container and the entering opening of the receptacle, to allow a heat medium to flow from the container into the receptacle, and a chamber communicating with the discharging opening of the receptacle and the entrance of the container. An air filtering device may be disposed in the casing for air filtering purposes, and for collecting and discharging water.

1. A heat exchanger comprising:
 a container including an inlet and an exit formed in a front portion thereof, and including an outlet and an entrance formed in a rear portion thereof and coupled to said inlet and said exit thereof respectively, said inlet of said container being provided for receiving a heat medium, 
 a receptacle including an entering port and a discharging port provided in a rear portion thereof and coupled together, for allowing a fluid medium to flow into and out of said receptacle, and including an entering opening and a discharging opening provided therein and coupled together, and 
 a casing disposed between said container and said receptacle and including a passage formed therein and defined by a duct, and coupled between said outlet of said container and said entering opening of said receptacle, to allow the heat medium to flow from said container into said receptacle, and out through said discharging opening of said receptacle, and said casing including a chamber formed therein and communicating with said discharging opening of said receptacle and said entrance of said container, for allowing the heat medium to flow from said receptacle into said container again after heat exchanging with the fluid medium. 
 
   
   
     2. The heat exchanger as claimed in  claim 1 , wherein said inlet and said outlet of said container are arranged diagonally. 
   
   
     3. The heat exchanger as claimed in  claim 1 , wherein said entrance and said exit of said container are arranged diagonally. 
   
   
     4. The heat exchanger as claimed in  claim 1 , wherein said entering port and said discharging port of said receptacle are arranged diagonally. 
   
   
     5. The heat exchanger as claimed in  claim 1 , wherein said discharging opening of said receptacle includes a cross sectional area greater than that of said entering opening of said receptacle, to allow the heat medium to flow from said entering opening to said discharging opening of said receptacle in a decreased flowing speed. 
   
   
     6. The heat exchanger as claimed in  claim 1 , wherein said chamber of said casing includes a cross sectional area greater than that of said passage of said casing, to allow the heat medium to flow through said casing and into said container in a decreased flowing speed. 
   
   
     7. The heat exchanger as claimed in  claim 1 , wherein said casing includes an air filtering device disposed therein, and disposed between said discharging opening of said receptacle and said entrance of said container, for air filtering purposes. 
   
   
     8. The heat exchanger as claimed in  claim 7 , wherein said casing includes a discharge orifice formed in bottom thereof, for receiving and collecting and discharging water filtered from the heat medium.
